Abstract
Description
- The present invention relates to a railway wagon for transport of for example a semi-trailer, comprising—carried by two bogies or the like—a main portion, pivotally connected to a rearward bogie, and a wagon end, connected to a forward bogie, the main portion and the wagon end being releasably connected to each other. It also relates to a method at a loading of a semitrailer or the like on such a railway wagon.
- It is well known in the art that in many instances it may be desirable to load a semi-trailer, normally intended for road transport, on a railway wagon and to transport it in a train on a railway so as to provide a more efficient and environmentally tolerable transportation.
- The loading and unloading of a semi-trailer on and off a railway wagon, built for this purpose, requires in its simplest form extensive equipment, such as cranes and/or heavy lift trucks, at specialized terminals. Also, the investments in and around such terminals of roads and handling areas are burdensome.
- A more favourable solution may be to allow for the possibility to pivot out a loading area for the semi-trailer from the remainder of the wagon, so that the semi-trailer can be rolled onto this loading area, which is then pivoted back in line with the wagon for rail transport.
- A typical example of this technique, falling within the definition under the heading Technical Field above, is shown in DE-A-32 34 374. The loading area is here pivoted out from the wagon on rolls or the like on a special ground plate. The investments in the infrastructure are still high.
- Another example of the same general nature is shown in EP-A-0 869 891 and EP-A-1 805 072. This wagon suffers from the disadvantages with the infrastructure demands and is furthermore heavy, complicated and expensive.
- A relatively early attempt to provide a railway wagon—not falling within the definition above—with a pivotable platform for a semi-trailer or a container is shown in GB-B-901 275. The pivotable movement of the platform is guided by beams on the wagon, and the beams may be pivoted out from the wagon. The platform, supported by support legs, has ramps for the rolling on and off of a semi-trailer.
- The main purpose of the invention is to provide a railway wagon of the kind defined above, which does not show the drawbacks described above. Especially, it shall be possible to load and unload a semi-trailer at any desired location without the provision of any special infrastructure in the form of special plates, surfaces or the like.
- THE INVENTION
- A railway wagon fulfilling the above requirements is according to the invention attained by the combination of a beam to be connected to or being connected to the wagon end for horizontally guiding the main portion at its pivoting out from the wagon end and means for vertically displacing the main portion or a part thereof in relation to the wagon end.
- Power is needed for maneuvering the main portion horizontally and vertically. If it is desired to keep the construction of the wagon as simple as possible, this power can be transferred from a power source external to the wagon through the beam. In other cases it may be more favorable to have an internal power source in the wagon for maneuvering the main portion. The power source may be pneumatic, hydraulic or electric.
- In a practical case with an external power source a beam assembly comprising the beam and two telescoping support legs can be connected to a working machine or truck, supplying the necessary power. The beam assembly is to be connected to the wagon end, before the main portion can be pivoted out.
- In the case with an external power source the beam can be attached to the wagon end and can be connected to a working machine or truck. The working machine or truck may in such a case be provided with a telescoping support leg for the beam.
- In the case with an internal power source the beam may be pivotally attached to the wagon end and be provided with a telescoping support leg at its end.
- A connection mechanism between the main portion and the wagon end may in a first embodiment comprise the means for vertically displacing the main portion in relation to the wagon end. Such a connection mechanism is preferably arranged at each lateral end of the main portion, so that access for a semi-trailer to the through-shaped main portion with an open end is possible.
- Each connection mechanism preferably has means for lifting the main portion somewhat from a locked neutral position in order to unlock the connection mechanism from the wagon end and for lowering the main portion to the ground.
- Especially in the case with an internal power source, the main portion may in a second embodiment be provided with telescoping control legs for its support on the ground, when it is pivoted out from the wagon end and disconnected from the beam.
- These control legs are preferably arranged in the vicinity of the free end of the main portion and are arranged to lower the main portion to the ground and to lift it again after loading or unloading of a semi-trailer. Alternatively, the control legs are arranged to lower a bottom ramp, pivotally attached to the main portion, to the ground and to lift it again after loading or unloading of a semi-trailer.
- As a special embodiment a wagon unit may comprise two wagons on a common Jacobs bogie, constituting the rearward bogie for each of the two wagons. Hereby, a six-axle wagon is created.
- A method at a loading of a semi-trailer or the like on a railway wagon as defined above is characterized in
- that a beam is arranged at or pivoted out from the wagon end in proper position for horizontally guiding the main portion,
- that the main portion is pivoted out from the wagon end guided by the beam,
- that the main portion is lowered by means for vertically displacing the main portion or a part thereof in relation to the wagon end, and
- that the beam is removed or pivoted in against the wagon end for allowing longitudinal entry of the semi-trailer.
- If the main portion is provided with telescoping control legs, these are lowered into supporting contact with the ground prior to pivoting in the beam against the wagon end, whereupon the main portion is lowered to the ground by means of the control legs.

FIG. 36 is an isometric view to a larger scale of slightly more than half of the wagon ofFIG. 31 in a pivoted out position. - A railway wagon for loading a semi-trailer thereon is shown in
FIG. 1 . The wagon has two bogies (or wheel sets): aforward bogie 1 and arearward bogie 2. Thebogies main portion 3 and awagon end 4. As is first clearly visible inFIG. 4 but then also in many other Figures, themain portion 3 and thewagon end 4 are movable in relation to each other, but in the transport position shown inFIG. 1 they are connected to each other and form an entity (or wagon that can be run on the railway). Themain portion 3 is pivotally connected to therearward bogie 2, whereas thewagon end 4 is pivotally connected to theforward bogie 1. - The
main portion 3 is intended to accommodate asemi-trailer 5, shown inFIGS. 10 , 11, 24, and 25, and is preferably through-shaped with an open end when pivoted out from thewagon end 4 and with longitudinal sidewalls. - The relative movability of the
main portion 3 in relation to thewagon end 4 has the purpose of enabling a rolling loading of thesemi-trailer 5 onto themain portion 3 in a position where themain portion 3 is pivoted out from thewagon end 4. - At the arc-shaped junction between the
main portion 3 and thewagon end 4 there is aslide arrangement 6 to enable the pivoting movement and locking means to lock themain portion 3 to thewagon end 4 in a transport position. Theslide arrangement 6 may as shown comprise three grooves in thewagon end 4 and threeprojections 6′ (FIG. 4 ) at each end of themain portion 3. - A
telescopic strut 7 may be arranged between themain portion 3 and thewagon end 3 at either side of the wagon for preventing breaking between these two portions, when they are pivoted in relation to each other. - In order to enable the pivoting out of the
main portion 3 to a position, in which a semi-trailer can be rolled onto the main portion, there is provided in the first embodiment shown inFIGS. 1-11 abeam assembly 8 powered and controlled by a working machine ortruck 9, for example of the type Bobcat®. - As is most clearly shown in
FIG. 2 , thisbeam assembly 8 mainly comprises an arc-shapedbeam 10 with twotelescoping support legs 11 extending perpendicularly thereto. The end to the left in the Figure of thebeam 10 may be provided with aguide pin 12 for cooperation with a corresponding hole at the grooves in thewagon end 4. At the opposite end of thebeam 10 there are connection means 13 for hydraulic connection between the hydraulic power source of thetruck 9 and a hydraulic system in thebeam assembly 8. - The
support legs 11 may be telescoped to a desired length individually by hydraulic motors therein, or alternatively one of thesupport legs 11 can have a hydraulic motor and the telescopic movement be synchronously transmitted by mechanical means to the other support leg. - The
beam 10 also contains a hydraulically powered driver (not shown) movably longitudinally therein for catching the end of themain portion 3 in a position with thebeam 8 in line with the grooves of thewagon end 4 and for transferring themain portion 3 in a pivoting movement along thebeam 8. -
FIG. 1 illustrates a starting position with the semi-trailer wagon in transport position and thebeam assembly 8 connected to thetruck 9. - In
FIG. 3 thebeam 10 has been brought in line with the grooves of thewagon end 4 and has been locked in this position. Thesupport legs 11 have been brought into supporting contact with the ground. - In
FIG. 4 themain portion 3 has been pivoted out in the beam 10 (after one of thestruts 7 has been disconnected). It may be noted, however, that at the end of this pivoting movement a side portion of the main portion has not left contact with thewagon end 4. - Before this pivoting movement can be accomplished, the
main portion 3 has to be disconnected from thewagon end 4. Reference is now made toFIGS. 5-8 for a description of this (and another) feature. - At its end neighboring the
wagon end 4, themain portion 3 is provided with aconnection mechanism 3A at each side. There are mechanical means—for example hydraulically operated from thetruck 9—within theconnection mechanism 3A for lifting and lowering the main portion in relation thereto and maintaining the attained positions. - In the stage immediately preceding the one shown in
FIG. 4 , themain portion 3 is lifted somewhat, as is shown inFIGS. 5 and 6 . By this movement, mechanical locking means between theconnection mechanisms 3A and thewagon end 4 will be released and the pivoting movement enabled. - When the pivoting movement is completed (
FIG. 4 ), theconnected strut 7 will be locked in order to prevent breaking between themain portion 3 and thewagon end 4. - Hereafter, the
main portion 3 is lowered in relation to theconnection mechanisms 3A until contact with the ground at the rail, as is shown inFIGS. 7 and 8 . - The
beam assembly 8 can now be removed by thetruck 9, as shown inFIG. 9 , leaving themain portion 3 open for backing in asemi-trailer 5 by means of a tractor unit. - In
FIG. 10 thesemi-trailer 5 is loaded on themain portion 3 and thebeam assembly 8 has again been brought into appropriate position against thewagon end 4 for enabling a return pivoting movement of themain portion 3. Themain portion 3 is lifted to the position shown inFIGS. 5 and 6 (some 100 mm over the transport position) and is pivoted into line with thewagon end 4. When themain portion 3 hereafter is lowered into transport position, theconnection mechanisms 3A will be locked to thewagon end 4 and the king pin of the semi-trailer will engage an appropriate attachment 14 (FIG. 1 ) therefore on thewagon end 4. - As shown in
FIG. 11 , the semi-trailer wagon is now ready for transport on its rail. An unloading process of the semi-trailer is performed in a corresponding but generally opposite way. - A second embodiment is shown in
FIGS. 12-15 . - In this embodiment the beam assembly is not separate from the wagon, but instead the
wagon end 4 is provided with abeam 15, which is pivotally journaled to the wagon end and may be folded out from a rest position, as shown inFIG. 12 to a working position, as shown inFIG. 13 . Each side of thewagon end 4 may be provided with such abeam 15 for enabling a pivoting out of themain portion 3 in either direction. In other respects, thebeam 15 has the same general design as thebeam 10 in the previous embodiment. - For the handling of the wagon at loading and unloading, a working machine or
truck 9, for example of the type Bobcat®, is needed. Atelescoping support leg 16 is connected to thistruck 9 by means of connection means 13, as shown inFIG. 14 . Thesupport leg 16 is connected to thebeam 15, as shown inFIG. 13 , for maneuvering by hydraulic power from the truck. - The design of the wagon according to this second embodiment is in other respects generally the same as for the wagon according to the first embodiment. Especially, it can be noted that also this wagon is provided with the
connection mechanisms 3A for lifting and lowering themain portion 3. - The function of the wagon is virtually the same as for the first embodiment, and therefore no detailed description is given. The function is illustrated in
FIGS. 12 , 13, and 15. - A third embodiment is shown in
FIGS. 16-21 . The main difference in relation to the previous embodiments, especially the one shown inFIGS. 12-15 , with which it has the closest similarities, is that the power for handling the wagon is not provided externally, such as from thetruck 9, but rather internally, such as an arrangement driven by electricity or by an internal combustion engine, preferably located in thewagon end 4. Pneumatic pressure available in a goods train can also be employed. As is well known to any person skilled in the art, such an arrangement for handling the wagon may for example be electro-mechanical, hydraulic or pneumatic with respective pros and cons. -
FIG. 16 shows a wagon with an internal power source in a transport position. - In
FIG. 17 abeam 18 has been pivoted out from its rest position (FIG. 16 ) against thewagon end 4. Ajack 19 at the beam end has been operated into supporting contact with the ground. Themain portion 3 has been lifted somewhat by theconnection mechanisms 3A for unlocking the latter from thewagon end 4, and thestrut 7 at thebeam 18 has been disconnected from thewagon end 4. - In
FIG. 18 themain portion 3 has been pivoted out in the beam 18 (with its inner end still supported by the wagon end 4), and themain portion 3 has been lowered into contact with the ground by theconnection mechanisms 3A. - In
FIG. 19 thejack 19 has been lifted from the ground, and thebeam 18 has been swung in to its rest position against thewagon end 4, so that themain portion 3 can be accessed from its free end. - In
FIG. 20 a semi-trailer has been backed onto themain portion 3, and thebeam 18 has again been pivoted out from thewagon end 4 and thejack 19 been lowered into contact with the ground. - In
FIG. 21 themain portion 3 has been pivoted back into rest position in thebeam 18, and themain portion 3 has been lifted, so that locking can be effected. The king pin of the semi-trailer may engage its attachment 14 (FIG. 16 ) on thewagon end 4. The only remaining action before transport is to lift thejack 19 from the ground and to swing thebeam 18 back into transport position against thewagon end 4. - A modification, mainly applicable to the third embodiment of
FIGS. 16-21 but in principle also applicable to the other embodiments, is shown inFIGS. 22 and 23 . In the previous embodiments, stabilizingstruts 7 are provided between themain portion 3 and thewagon end 4. In the present modification a stabilizing function is instead provided by asupport yoke 20 applied downwards against the rail by means (not shown) in thewagon end 4 at the handling of the wagon in the way described above. - Another, slightly different railway wagon for loading a semi-trailer thereon is shown in
FIG. 24 . Also this wagon has two bogies (or wheel sets): aforward bogie 1 and arearward bogie 2. Thebogies main portion 3 and awagon end 4. As is first clearly visible inFIG. 25 but then also in many other ofFIGS. 26-30 , themain portion 3 and thewagon end 4 are movable in relation to each other, but in the transport position shown inFIG. 24 they are connected to each other and form an entity (or wagon that can be run on the railway). Themain portion 3 is pivotally connected to therearward bogie 2, whereas thewagon end 4 is pivotally connected to theforward bogie 1. - The
main portion 3 is intended to accommodate a semi-trailer (not shown) and is preferably through-shaped with an open end when pivoted out from thewagon end 4 and with longitudinal sidewalls. - The relative movability of the
main portion 3 in relation to thewagon end 4 has the purpose of enabling a rolling loading of thesemi-trailer 5 onto themain portion 3 in a position where themain portion 3 is pivoted out from thewagon end 4. - At the arc-shaped junction between the
main portion 3 and thewagon end 4 there is a slide arrangement to enable the pivoting movement and locking means to lock themain portion 3 to thewagon end 4 in a transport position. The slide arrangement may comprise grooves in thewagon end 4 and projections 6 (see especiallyFIG. 28A ) at each end of themain portion 3. - In order to enable the pivoting out of the
main portion 3 to a position, in which a semi-trailer can be rolled onto the main portion, there is provided abeam assembly 8, preferably hydraulically powered and controlled. - This
beam assembly 8 mainly comprises an arc-shapedbeam 10 with atelescoping support leg 11 extending perpendicularly thereto. Thesupport leg 11 may be telescoped to a desired length by a hydraulic motor therein. - As is most clearly shown in
FIG. 28A , themain portion 3 is at each side provided with atelescoping control leg 22, preferably hydraulically operated. - Hydraulic means are provided for pivoting the
main portion 3 in relation to thewagon end 4 between a transport position shown inFIG. 24 (although thebeam assembly 8 is folded in against thewagon end 4 in that position) and a loading and unloading position shown inFIGS. 25-28 . - For powering the different hydraulic means on the wagon the wagon may be provided with an on-board hydraulic power source.
-
FIG. 24 illustrates a position in which thebeam assembly 8 has been folded out from its transport position against thewagon end 4, whereas themain portion 3 is still in the transport position. - In
FIG. 25 thesupport leg 11 has been lowered into supporting contact with the ground, and themain portion 3 has been pivoted out from thewagon end 4. - In
FIG. 26 thecontrol legs 22 have been lowered into contact with the ground and also lifted themain portion 3 somewhat out of engagement with thebeam 10. - In
FIG. 27 thebeam assembly 8 has been folded in against thewagon end 4, and inFIG. 28 thecontrol legs 22 have lowered themain portion 3 down to the ground, so that a semi-trailer (not shown) can be backed onto the main portion. - Hereafter, the operation is basically reversed, so that the wagon reaches the position shown in
FIG. 24 , whereupon the beam assembly is folded in against thewagon end 4, so that the wagon can be transported along its rail. - A fifth embodiment of the wagon according to the invention is shown in
FIGS. 29 , 29A, and 30. This embodiment has many similarities with the fourth one, and like numerals are used for like parts. - The difference is mainly that in the fifth embodiment the
main portion 3 is provided in its end facing thewagon end 4 or its end pivoting out therefrom with abottom ramp 23, pivotally attached the remaining bottom of themain portion 3. Thisramp 23 is connected to thecontrol legs 22, so that when these are lowered to the ground, also thebottom ramp 23 is lowered, enabling a semi-trailer to be backed onto themain portion 3, which otherwise remains in its horizontal position. - Alternatively—but not shown—the
control legs 22 downwardly end in thebottom ramp 23, so that it is the bottom ramp that is lowered to the ground. - A sixth embodiment of the wagon according to the invention is shown in
FIGS. 31-36 . This embodiment has basic similarities with the embodiments shown inFIGS. 24-30 in that the wagon preferably is provided with at least one on-board power source and hydraulic means for operation of the wagon. However, this wagon may alternatively be constructed in the same way as the embodiments shown inFIGS. 1-23 , where power for the operation of the wagon is externally provided. - The previously shown and described semi-trailer wagons are each provided with two bogies, one towards each end. However, it is not uncommon that two (or even more) such wagons are coupled together into a wagon unit by means of a special common bogie, called a Jacobs bogie.
FIGS. 31-36 thus illustrate a six-axle wagon with a two-axle bogie towards each end and a two-axle Jacobs bogie 30 in the middle. This wagon is functionally nothing else than two “ordinary” wagons connected by a Jacobs bogie. - With reference to
FIG. 31 , each such wagon has aforward bogie 1, a rearward bogie 2 (which happens to be one and the same Jacobs bogie 30), amain portion 3, and awagon end 4. Eachmain portion 3 can be pivoted out, as described above.FIGS. 34 and 35 are meant to illustrate that the twomain portions 3 may be pivoted out in the same direction or in opposite directions. -
FIG. 36 is meant to illustrate to a larger scale slightly more than a half of this wagon supported in the middle by aJacobs bogie 30. It is evident also from this illustration that the design for pivoting out themain portion 3 generally corresponds to the design in the embodiments shown inFIGS. 24-30 - Modifications are possible within the scope of the appended claims.
